I don't know if you mean this, but I can tell 2 ways that are too easy..!
1) If you want to create a new clone widget (and make some small changes on the second one) go to the XWidget's folder and simply make a copy of the widget's folder. Then rename the folder like "xxx 2" or whatever. Then open the XWidget dock with the installed widgets, right click - Refresh to appear the new widget. Edit the new one and change the name of the widget (same as the folder)
2) XWidget has default tag code for the right click options to duplicate the running widget. (I use it for the hdd widgets or for the aquarium fishes)
XWidget designer has all lot of ready functions through the tags. I don't understand why you don't want to use them...
